The successful construction of complex natural products depends to a large extent on how efficiently key intermediates can be generated. Here we report our efforts towards the first total synthesis of tedanolide (1), employing Evans’ aldol methodology in combination with a vinylogous Mukaiyama aldol reaction (VMAR) and Sharpless’ asymmetric dihydroxylation. This protocol allows for rapid access to its numerous chiral centers.

天然产物的成功合成在很大程度上依赖于关键中间体的高效生成。在此,我们报告了我们在完全合成tedanolide (1)方面的努力,采用了Evans的醇醛法,结合了
乙烯基MukayaMA醇醛反应(VMAR)和Sharpless的非对称二羟基化。该方案允许快速获得其众多手性中心。
